[QUOTE="stones, post: 1376771, member: 540734"] For a hard hitting sub look for something with a great deal of volume displacement (Vd). That "hit" you describe is nothing more than a single large push of air from the subwoofer. Smaller drivers like tens and eights need to be run in multiples in order to give a strong impact, high excursion 12's can do the job while large subs like fifteens and larger have a much easier time creating strong subsonic impacts due to their increased cone area. Ported enclosures help to increase impact by letting the bass energy off the back of the sub rienforce the front, this helps assist smaller or excursion limited subwoofers displace more air. A sealed enclosure can only use the energy from the front of the cone, strong impact can be had out of a sealed enclosure but multiple, large or high excursion drivers are nesessary. A high excursion driver is one with an electrical Xmax (motor driven) of 13mm or more in one direction(26mm total or greater than 1inch) while limited drivers are less then 12mm in one direction (24mm total or 1inch or lesser). One thing to keep in mind is that excursion alone does not determine the sound quality of the woofer it is just one more thing to keep in mind when designing the system. What did you have in mind for your sub system design? Sealed or ported? 8's,10's,12's,15's ? Single sub or mutiple subs? How much room is there to work with? What kind of wattage do we have to work with? [/QUOTE]
